References for Revelation 5:1
and I saw a mighty angel proclaiming with a loud voice, "Who is worthy to open the scroll and break its seals?"

Then I saw between the throne and the four living creatures and among the elders a Lamb standing as if it had been slaughtered, having seven horns and seven eyes, which are the seven spirits of God sent out into all the earth.
